College tuition, diversity, and pay

• Many people are interested to know about the tuition, costs, diversity and potential salary when searching for college.
• In this project, we want to analyze:

1. diversity among schools across US
2. tuition costs across different states
3. historical trends of tuition
4. average potential salary for graduates from different universities

• We have 4 datasets with 23 variables and more than 50000 observations.

• we are interested to know whether there is any correlation between enrollment rate and each diversity group
• we did the exploration for both in state and out of state tuition in the next slides
